Help Needed! Diamond speed star A50 for W98

I have had the misfortune of computer problems necessitating that I reformat my hard disk. After that I needed to reinstall the drivers. My video driver was Diamond speed star A50 for W98. Unfortunately since purchasing my computer approx 18 months ago I have managed to loose one of the 2 floppy disks which came with the Diamond speed star card. I have been to the latest site for Diamond but cannot see any reference to Diamond speed star A50 for W98. I do not wish to pay approx $150 for a new video card.
Any suggestions of what can be done will be greatly appreciated.
